Setting 2: Drive Dedicated Motor (constant torque, 1:10)
Use this setting when operating a drive duty motor with a torque ratio of 1:10. This motor type is allowed to run with
100% load from 10% up to 100% speed. Running slower speeds with full load can trigger an overload fault.

Setting 4: PM Motor for Derated Torque
This setting is for operating a PM motor for derated torque. This motor has a self-cooling design, so the overload
tolerance drops as the motor slows. Electronic thermal overload is triggered in accordance with the motor overload
characteristics, providing overheat protection across the entire speed range.

Overload Characteristics
at 100% Motor Load
Continuous operation with 100% load
from 6 Hz to 50/60 Hz.
Overload Characteristics
at 100% Motor Load
Continuous operation with 100% load
from 0.6 Hz to 50/60 Hz.
Overload Characteristics
at 100% Motor Load
Reaching 100% when operating at below
the base frequency will cause a motor
overload fault (oL1). The drive fault
output closes and the motor coasts to
stop.
